Title: Pressure relief valve
Inventor: SNELL MARTIN
IPC: F16K17/04
Filed: 1995-06-16
Abstract: In a pressure relief valve a disc 22 co-acts with an annular seating and O-ring seal 14 in a circumferential flange 4 around an aperture 6 in a pressured housing 2. The disc is urged into contact with the O-ring seal 14 by a Belleville spring washer 24 held in position by bolts 26 and washers 28. In use, should a slight excess of a pre-determined pressure differential arise across the disc, the Belleville spring washer flexes slightly to permit venting. Should a sudden, rapid, rise of gas pressure within the housing 2 occur, the Belleville spring washer snaps-over to permit rapid release of the excess gas pressure. The disc 22 may be of laminated glass or acrylic plastics. The housing 2 may accommodate electrical equipment, such as a circuit breaker. <IMAGE>

Title: Method of manufacturing a component for an electromagnetic friction clutch assembly.
Inventor: UNGRUE JAMES R
IPC: F16D27/112
Filed: 1996-11-05
Abstract: A method for manufacturing a component for use in an electromagnetically actuated clutch (10), such as an armature (14) or a pole piece (16), having one or more flux breaks provided therein includes the initial step of providing a mould (20) having an upstanding central post (21) which defines an annular mould cavity (22). A quantity of powdered metal material (23) is disposed within the mould cavity (22). The powdered metal material (23) is formed from a magnetically permeable material, such as a ferromagnetic material. Next, one or more preforms (30) of a non-magnetically permeable material are disposed within the mould cavity (22). The preform (30) is placed on top of the quantity of powdered metal material (23) axially above the desired location for the magnetically non-conductive region of the component to be formed. Then, a ram (40) of a press machine is moved axially downwardly into engagement with the preform (30) and the powdered metal material (23) contained within the mould (20). As the ram (40) moves downwardly, it initially engages the preform (30), moving it axially downwardly through the powdered metal material until the preform (30) engages the lower surface of the mould (20). Further downward movement of the ram (40) compresses both the preform (30) and the powdered metal material (23) into a single integrated component preform (50). Lastly, the ram (40) is retracted to permit removal of the component preform (50), and the component preform (50) is placed in a conventional sintering oven to form the final component (14).

Title: Pitch extraction in a speech processing unit
Inventor: LEE SEE-WOO
IPC: G10L25/90
Filed: 1997-02-12
Abstract: A method of extracting at least one pitch from every frame, includes the steps of generating a number of residual signals revealing highs and lows of speech in a frame, and taking one satisfying a predetermined condition among the residual signals generated as the pitch. In the step of generating the residual signals, the speech is filtered, using a finite impulse response FIR-STREAK filter which is a combination of a FIR filter and a STREAK filter and the filtered signal is output as the residual signal. In the step of generating the pitch, only the residual signal whose amplitude is over a predetermined value, and whose temporal interval is within a predetermined period of time is generated as the pitch. Alternatively residual signals may also be interpolated with reference to their relations to preceding/succeeding residual signals and then the pitch may be extracted from the generated or interpolated residual signals.

Title: cOMMUNICATION SYSTEM HAVING A REDUCED DATA RATE FOR HIGH TRAFFIC LEVELS
Inventor: KING NIGEL JONATHAN RICHARD
IPC: H04W84/14
Filed: 1997-12-23
Abstract: In a fixed wireless access system, the amount of data traffic at a base station 18 is monitored and when it exceeds a predetermined level, the data rate of transmissions between residential transceivers 14 and the base station is reduced to increase the number of user channels available, i.e. when available data bandwidth and/or the number of free channels falls below a threshold, a reduced rate coding scheme is implemented. Uplink and downlink data rates which may be symmetric or asymmetric are reduced to the same or different rates. If a data call is detected and there is insufficient bandwidth for the maximum data rate, a lower data rate is selected. It is also possible to change the data rate during a call. When it is determined that there is insufficient available bandwidth, successive calls in progress have their data rate reduced until enough capacity is made available. The system may operate on demand with data yielding to voice calls. The system may also provide tiered service levels with guaranteed higher data rates for premium customers.

Title: Buffer overflow and underflow control for facsimile transmission.
Inventor: HO GRANT I
IPC: H04N1/32
Filed: 1999-02-24
Abstract: In a facsimile system, buffer underflow is prevented by forcing the transmit pointer to wait at a current end-of-line (EOL) symbol and transmit fill bits until there are at least two EOL symbols stored in the buffer. Buffer overflow is controlled by selectively dropping lines if the write pointer approaches too close to the transmit pointer and the difference between successive lines is sufficiently small (selective line-dropping), dropping lines whenever a permitted maximum buffer size is exceeded, and gradually changing the permitted distance between transmit and write pointers and permitted maximum buffer size as the image is scanned to accomplish a smooth buffer flushing.
